StatsD displaying "go_gc_duration" metrics but not the airflow metrics

Question

We have installed statsD exporter by following steps..

pip install 'apache-airflow[statsd]'

Added below config details

statsd_on = True
statsd_host = localhost
statsd_port = 8125
statsd_prefix = airflow

And then downloaded the below zip file

https://github.com/prometheus/statsd_exporter/releases/download/v0.21.0/statsd_exporter-0.21.0.linux-amd64.tar.gz

And then executed the below command

./statsd_exporter --statsd.listen-udp localhost:8125 &

statsd metrics is started but it is showing the "go_gc_duration" stats like below but airflow stats are not being displayed.

go_gc_duration_seconds{quantile="0"} 1.1717e-05
go_gc_duration_seconds{quantile="0.25"} 1.5126e-05
go_gc_duration_seconds{quantile="0.5"} 1.9535e-05
go_gc_duration_seconds{quantile="0.75"} 4.3568e-05
go_gc_duration_seconds{quantile="1"} 0.000384508
go_gc_duration_seconds_sum 669.380082897
go_gc_duration_seconds_count 8.186899e+06

but expected metrics should be as below

# HELP airflow_collect_dags Metric autogenerated by statsd_exporter.
# TYPE airflow_collect_dags gauge
airflow_collect_dags 50.056391
# HELP airflow_dag_loading_duration_example_bash_operator Metric 
autogenerated by statsd_exporter.
# TYPE airflow_dag_loading_duration_example_bash_operator summary
airflow_dag_loading_duration_example_bash_operator{quantile="0.5"} 1.108e-06
airflow_dag_loading_duration_example_bash_operator{quantile="0.9"} 4.942e-06

is there something we have to do changes or missed, pls any suggestions

Answer 1

Actually or not, by reference https://quay.io/repository/prometheus/statsd-exporter

./statsd_exporter --statsd.listen-udp localhost:8125 --log.level debug

Answer 2

Same thing was happening to me. In the airflow.cfg there is another option called statsd_allow_list = airflow : I deleted it, restarted AF and it's working
